考虑了剪切变形和转动惯量对细长梁振动的影响。该理论包含了一个剪切系数，这是以前许多研究的主题。本文导出了一个新的剪切系数公式。对于圆形截面，所得的剪切系数与大多数作者认为的“最佳值”完全一致。''找到了许多不同横截面的剪切系数。
The Timoshenko beam theory includes the effects of shear deformation and rotary inertia on the vibrations of slender beams. The theory contains a shear coefficient which has bren the subject of much previous research. In this paper a new formula for the shear coefficient is derived For a circular cross section the resulting shear coefficient that is derived is in fill agreement with the value most authors have considered "best.'' Shear coefficients for a number of different cross sections are found.
